结肠镜检查肠道准备研究热点的可视化分析

Visualization analysis of research on pre-colonoscopy bowel preparation

背景肠道准备是结肠镜检查前的必要环节,其研究主题较为分散.掌握肠道准备的研究现状及发展趋势,对于疾病研究和实际临床工作具有重要的价值,而目前该领域采用文献计量学的形式对此进行归纳和总结的研究是缺乏的.目的了解结肠镜检查前肠道准备相关研究在国内外的研究热点和发展趋势,以为研究者及临床工作者提供指导价值.方法检索建库至2022-09-10中国知网(CNKI)、万方、维普、中国生物医学文献数据库(CBM)、Web of Science核心数据集中与肠道准备主题相关的文献,采用CiteSpace 6.1.R3软件对年发文量、国家、机构、发文作者、关键词及聚类、文献共被引情况进行可视化分析.结果共分别纳入中、英文文献2340篇、2674篇,年发文量均呈逐年上升趋势,国际上最高产作者为Hassan Cesare,最高产国家为美国、韩国、英国等,国内最高产作者为孟小芬、张媛媛、钮美娥,最高产机构为苏州大学第一附属医院、中国人民解放军总医院、西安交通大学附属第二医院,研究热点为肠道准备质量、肠道准备方案的研究、特殊人群的肠道准备.结论国内外肠道准备相关的研究具备一定研究基础,国内研究能紧跟国际研究热点,但国际间、团队间合作仍需加强,未来应扩大基于更广泛人群的、更契合大数据时代发展的肠道准备相关研究产出,以为临床提供更高质量的研究证据.

BACKGROUND Bowel preparation is an essential step before colonoscopy,and its research topics are relatively scattered.Under-standing the research status and development trend of bowel preparation is of great value for disease research and actual clinical work.However,there is currently a lack of research in this field in the form of bibliometrics.AIM To understand the research hotspots and development trends of bowel preparation during colonoscopy around the world.METHODS The literature about the topics of bowel preparation was retrieved from the CNKI,Wanfang,VIP,China Biomedical Literature Database(CBM),and Web of Science core datasets from the inception of the database to September 10,2022.CiteSpace 6.1.R3 was used to visually analyze the annual number of publications,countries,institutions,authors,keywords,clusters,and co-citation literature.RESULTS A total of 2340 Chinese and 2574 English publications were included,and the number of annual publications showed an increasing trend from year to year.The author with the largest number of publications worldwide was Hassan Cesare,and the most productive countries included USA,Korea,UK,Italy,and China.Meng Xiao-Fen,Zhang Yuan-Yuan,and Niu Mei-E were the China’s most prolific authors.The First Affiliated Hospital of Suzhou University,the General Hospital of the Chinese People’s Liberation Army,and the Second Affiliated Hospital of Xi’an University were the most prolific institutions.Research hotspots focused on the quality of bowel preparation,the design of bowel preparation programs,and special groups for bowel preparation.CONCLUSION Studies related to bowel preparation have certain foun-dations,and China’s research can follow international hotspots,but cooperation among countries still needs to be strengthened.We should expand the research output related to bowel preparation based on a broader population and more suitable for the development of the era of big data,to provide higher quality research evidence for clinical practice.©The Author(s)2023.Published by Baishideng Publishing Group Inc.All rights reserved.
